I installed this on 3.6.5. There were a couple of glitches:
- the forum url and home url ($vbulletin->options['homeurl']) have to be the same for the proper redirect URL to be constructed for the Identity Provider
- the profilefield table doesn't have a title field, so the code which tries to discover the profilefieldid of the OpenID field in the user profile doesn't work - I worked around that by hardcoding the profilefieldid (there must be a way to discover that!)
Now works great with iNames!
